Wider Folding Trailed Combi-Disc offers High Output, Single Pass Cultivation
HE-VA has launched a further upgrade of its popular trailed Combi-Disc, with the new 450 and 550 models offering wider widths of 4.5m and 5.5m respectively, to provide growers with higher output, single pass machines for subsoiling, surface cultivation and consolidation.
The new models can be specified with either shearbolt or hydraulic auto-reset legs.
Ease of adjustment has been built into the design, so that the depth of both the subsoiler legs and discs can be hydraulically adjusted from the tractor seat. This allows the operator to make independent adjustments on the move for accurate control of cultivations. It can also be used as a subsoiler with the discs lifted out of work, a set of discs with the legs lifted up or as a complete one pass soil cultivator, all controlled from the cab.
There are seven hydraulic reset tines on the 450 Combi-Disc which subsoil to a 350mm depth, with quick-change replaceable points. The 550 version has 9 legs. Optional low-disturbance subsoiling tines and points are also available.
The 510mm diameter scalloped Sabre discs which follow the subsoiler legs will cut and mix to a depth of 125mm. The two rows of opposing discs can be hydraulically adjusted and, as they are pushed deeper in the soil, the angle of the disc is automatically altered, increasing their aggressiveness, to thoroughly mix and chop crop residues. The large, 700mm V profile press roller which follows gives good consolidation to leave a weatherproof finish.
Commenting, James Woolway, OPICO’s Managing Director said, ‘The new folding Combi-Discs are ideal for rapid ground coverage, with wider working widths and higher horse-power rating, increasing the work rate without compromising on soil management.Machines are equally at home being used for shallow stale seedbed preparation on 180hp tractors, or working up to 350mm deep moving the whole soil profile on a 450hp tractor.’
There is an optional minimal disturbance disc opener available. This slices through the surface layer in front of the subsoiling leg to reduce soil burstand ensure weed seeds are not brought up to the surface from depth.HE-VA Trailed Folding Combi-Disc 450 model
The Combi-Disc is an excellent tool for working ploughed land prior to drilling or for incorporating stubble and organic matter in a min-till system. A seeder kit can be added to plant cover crops or oilseed rape whilst cultivating, the seed is distributed behind a soil mat to ensure soil throwfrom the discs does not disrupt seed distribution.
The 450 and 550 models fold to a transport width of 2.61m and have automatic transport locks for safe and simple road transport.
